Re: ntsec and sshd question

[Karl M]

Hi Corinna...

I changed the CYGWIN setting and rebooted a couple of times to see...

With 'CYGWIN=ntsec tty' there is an extra process visible (ps -aef).

With 'CYGWIN=ntsec' there is no extra process visible.

I understand the spawning to authenticate eash login, but why does sshd 
spawn an extra time?

If it did not spawn an extra time, stopping the srvany service would do the 
right thing, ie stopping the sshd daemon.

In the *nix world, you want to run detached, but as a winnt/win2k service, 
you do not.

Thanks,

...Karl

Dunno. Could you try "CYGWIN=nontsec tty" and "CYGWIN=ntsec notty"
to check which setting raises that behaviour?

Hi Corinna...

But I did not see it before I set 'CYGWIN=ntsec tty'. When I had no value 
set for the CYGWIN variable, I did not see the extra sshd process. Why is it 
different now?

Thanks,

...Karl

It's normal. It's the parent sshd which has been started by
SRVANY and which has forked the daemon. It's not needed
anymore but for some reason SRVANY blocks that the process
can exit. if you stop the service (`net stop sshd') you
will see that SRVANY and the first sshd process have exited
but the daemon itself remains and is fully funtional.

ntsec and sshd question

[Karl M]

Hi All...

I just turned on 'CYGWIN=ntsec tty' and set up my file protections to make 
sshd happy (running as a srvany service on win2k sp1).

myname@MACHINENAME ~
$ ps -aef
     UID     PID    PPID TTY     STIME COMMAND
  system     652       1   0  15:39:34 /usr/sbin/sshd
  system     800       1  -1  15:39:39 /usr/sbin/sshd
  myname    1272       1   1  15:41:23 /usr/bin/bash
  myname    1104    1272   1  15:41:30 /usr/bin/ps

When I rebooted my machine and did a ps, I saw an extra sshd process that I 
did not see before. ssh/sshd appear to work fine. Why is there an extra sshd 
process...is it normal...does anyone else have the same thing happen?

Thanks,

...Karl
